Help please

I need some help my friends please. I was changing my valve cover gasket. But when I pull out the valve cover this part that I circled in the valve cover fell beneath the camshaft bearing ledge (inlet cam). I also circled where in the second picture. I am no mechanic, so when I couldn’t take that part out I thought that I could remove the cam bearing ledge to be able to remove the part that fell inside. I turn the 2 bolts I circled in the picture with red 1/2 turn, ONLY 1/2 turn counterclockwise. When I did that I heard a “gush” like if something underpressure was unlocked and an strong oil smell was released.
After that, I was afraid so I readjusted both bolts immediately with my wrench as hard as I could. Again, it was only those 2 bolts 1/2 turn counterclockwise and then I adjust it back as hard as I could but not extremely hard!
I put everything back together including new gaskets.
When I turned on the car, the car did 1 rev up to 1,800 rpm and went back to normal but I got the check engine light with 2 codes
2A82
2A98

The car runs smooth, strong, fast, no other issues except everytime I turn on the car, it does that 1 abnormal rev and then everything is back to normal.
Do you think the 2 error codes could be related to the fact that I did not adjust those 2 bolts to the correct inch/pound?
Or does the solution would be to get the BMW tool for the inlet cam, take out all the inlet cam bolts and adjust all of them to the correct inch/pound?
Or the error code is related to that little thing that is still inside beneath the inlet cam bearing ledge?
It can’t be the VANOS solenoid because I changed them less than 6 months ago and there were no error codes or check engine lights before this happened to me.
Thank you for your help

NOTE: By the way, the 2 bolts I messed up with are kind of in the middle of the inlet camshaft bearing ledge

After reading this post, I am wondering if you were able to get that piece out? also, Those 2 cam ledge bolts that you loosen and retighten has a torque specification. I read that you loosened it 1/2 turn but when you tightened it, you went beyond that 1/2 turn? is that right? in my opinion, 1) you over tightened those 2 camshaft ledge bolts causing the camshaft to bind. this could be the cause of your codes. 2) have you gotten out that piece that fell inside? that could also be the cause of your problems too. here is a link from this site with codes that you have.

hope this helps. I wouldnt run my car or keep driving it as if nothings wrong. these error codes are there for a reason and needs to be fixed.

good luck

I have a loud constant lifter tick. so I am sure one is stuck and I REALLY don't want to spend 18 hours of my life and several hundred in tools and parts. I was wondering if I remove the valve cover would I have enough access to spray some carb cleaner or maybe a full syringe of lacquer thinner down into the lifter and let it soak in to free it up? Once freed I am sure it would clean out since unlike the last owner I plan to do frequent oil changes in this car. When I bought it the engine oil was very black and about 2.5 quarts low. The poor car only has 75,000 miles. Of course I know that if I spray anything foreign into the lifters I would need to flush the area with fresh oil then drain and change all my oil, maybe even twice after running the car for a few minutes on the new oil.

I would use Liquid Moly oil sludge flush. There are really positive reviews on that stuff.

I am actually on my second engine flush. I have used some Marvel Mystery Oil and now I have 2 quarts of Rislone in fresh oil. I have only run the car for about 2 hours total with the Rislone, (I am not able to drive it much, no tags yet) and I don't think this problem will flush out. The last owner must have neglected the hell out of this car.
I just ordered the cam alignment tool, new Teflon seal rings and 2 new vanos bolts. I found 24 new lifters on e-Bay for about $70 but at that price I am skeptical. They show the right part # of 11 33 7 548 690 along with many others that these are supposed to be compatible with. Has anyone bought the cheap e-Bay lifters before?

I haven't used the eBay lifters but was looking at the Pelican Parts OE lifters they list. IMHO, I would use the OE version.
Makes me wonder if the previous owner waited 15K or longer to execute the oil changes.....

I bought this car from Copart Auto Auction so I really have no way of knowing the history but I am sure this idiot waited a LONG time between oil changes. I actually ordered BOTH. I got 12 of the INA brand lifters from FCP Euro for about $135 shipped and a set of 24 generic ones from eBay for just under $70. I got both in the mail today and I think they are identical except for one thing I noticed. The oil hole on the side of the INA brand lifters is just a little bit larger than the eBay ones described for the N52 engine. They supposedly cross with the same part number but I am sure the larger oil hole is the way to go. I am thinking of opening one up to see if they are the same on the inside but I am pretty sure they will be. I am not eager to be a Guiney pig but I bet that if you drilled the oil hole a little larger the eBay ones would be just fine. Like I said they look identical. I may upload some pictures in the interest of providing info for the community.

Well, I am doing replacing all my lifters just to be safe. I took everything apart and cannot tell which ones are bad or good and I could not get them apart. I figured they probably have some wear and if some are not able to hold pressure how would I know? I cannot see putting the whole car back together just to hear more tapping. Just like this write-up I had to shave my locking pin since it would not go into the flywheel.

I have found an problem though. I have 2 oil drain holes on the exhaust side of the head that won't drain oil at all. I need to figure how to clean them out without messing up anything else. I have arrows pointing to the ones that don't drain, holes 1 and 4 starting at the front of the head. Any clue on where this oil drains to? Does it drain straight to the pan or does it go into a crank bearing, etc.? I want to make sure it is safe to spray some car cleaner in there to soak and clean them out.
